Former Member — Thu, 21 Jul 2005 05:51:37 GMT

Hi all,

I have displayed data in alv grid now if user click on any field i have to process further. I'm not able to call interactive events. Please suggest.

Thanks,

Anup.

Hi Anup,

To be able to handle the events, you will have to register them. you have not specified whether you are using the Function Module approach or the OO approach.

Look at the demo program BCALV_TEST_GRID_EVENTS. It should help you understand how this is done. If you have further doubts, please get back.

Anand Mandalika.

Hi Anup,

If you are using "REUSE_ALV_LIST_DISPLAY", then there will be one field by name

" i_callback_user_command = g_f_callback_user_command ".

you uncomment that field.

for that user command write perform.

FORM user_command USING i_f_ucomm LIKE sy-ucomm

i_r_selfield TYPE slis_selfield.

CASE i_f_ucomm.

WHEN '&IC1'.

PERFORM fcode_item_lines USING i_r_selfield.

endcase.

now in this perform you code what has to be displayed.

Hi anup,

You can display data using ALV’s function module like

REUSE_ALV_LIST_DISPLAY .

To handle the events use SLIS structure.

To get the information about the field on which the user has clicked use

GET CURSOR FIELD <fname> VALUE <fvalue >. in AT LINE-SELECTION event.

I hope it may help u.

With regards…

Prasad.

Hey Anup,

Did u check the sample code I have attached.

It will work fine. It's very simple buddy.

Try it and let me know by EOD.
